MMR Big Tube ?????

Question for all you guys.
MMR intake seems like a nice straight tube but do you guys think it will effect performance in a negative way since its not in a closed unit and might have heat soak issue. Also is there a possibility the unit might suck in water from regular driving?
I honesly am not looking much at a huge performance gain but I like aound factor that it intesifies the turbo suction:headbonk:

The intake moves the filter outside of the engine bay so heat soak really isn't an issue. There is a possibility it would suck in water, but in my experience it is minimal. I had a JLT cold air on my Cobra and drove in terrible wet and flooded conditions without issue. Others may have different experiences though.

I have the same concerns. The MMR looks nice, adds some nice sound, and probably adds some power... But I'd hate for it to be at the sake of heat soak or getting water into the engine.

The ride height is pretty up there in this car to begin with, plus the whole filter would have to be submerged to get water in the engine. It really is of no concern unless you are fording rivers.

The intake sits in the fender well about a foot above the road. If you're in water that deep you have bigger problems than hydrolocking. On mine this will be different as I've gone with a better filter. Here's a picture reference:



I'll install mine today and let you know about the IATs.

The stock box is fantastic but I didn't want to go through the trouble of deleting the resonator, and the MMR unit looks very good.

What filter did you go with? Will the K&N filter not be good for use in AZ?

I bought a Donaldson Powercore filter distributed by Volant. Donaldson are the folks who came up with the induction system for the M1 Abrams tank. Oiled fabric filters perform very poorly on the ISO A2 fine dust test. The kicker is that A2 test dust is sold as "Arizona" dust.

These are the best articles I've found so far:

I'm sure 90% of folks will be fine with a K&N, but I prefer.. overkill.

IIRC S&B also makes paper filters in cone form that would do nicely.

Great info. Thanks.

Can you post a video on here of the MMR intake vs stock?

MMR has one up, but maybe I'll make a recording from inside the cabin. I'm kinda delaying the installation right now because there's some sort of coating inside of the tube that seems to be peeling in one spot. I need to find out what it is so I can re-coat it.

What part of AZ are you in OVRKILL?

Pics of peeling?

I don't get the placement of this, though. Wouldn't all airflow be blocked by the bumper cover?

If you're concerned about dust, dirt, mud, water, etc.... then you could use a prefilter from K&N or an Outerwear. I've used them for many years on different vehicles that I drive and race and they offer good protection while not hurting performance. They are used primarily for off road racing but they work very well in other applications. The only downside is that they are expensive for what they are.

Here's a link to a YouTube of an old one that I have showing how well they repel water.

Why would they put coating on inside of tube?
